WINID-SHIELD HINGE.

T 0 all whom it may concemr Be it known that we, ARANT J. KRABER andGEORGE F. F ERRIER, citizens of the United States of America, residingat Pitts burg, in the county of Allegheny and State of Pennsylvania,have invented certain new and useful Improvements in l/Vind-ShieldHinges, of which the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates to automatic wind shield hinges and has for itsobject to provide a hinge of such class, in a manner as hereinafter setforth, whereby the upper section of a wind shieldcan be angularlyadjusted with respect to the lower section, and maintained in theposition to which it has been adjusted.

Further objects of the invention are to provide a wind shield hinge,which is comparatively simple in its construction and arrangement,strong, durable, efficient in its use, readily set up in operativerelation with respect to the two sections of the shield, andcomparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists ofthe novel construction, combination, and arrangement of parts, ashereinafter more specifically described and illustrated in theaccompanying drawing, wherein is shown the preferred embodiment of theinvention, but it is to be understood that changes, variations, andmodifications can be resorted to, which come within the scope of theclaim hereunto appended.

In describing the invention in detail, reference is had to theaccompanying drawing, wherein like reference characters denotecorresponding parts throughout the several views, and in which:

Figure 1 is a side elevation of the hinge. Fig. 2 is a front elevationof the same. Fig. 3 is a side elevation of the female member of thehinge. Fig. 4: is a similar View of a portion of the male member of thehinge. Fig. 5 is a vertical longitudinal sectional view of the hinge.and Fig. 6 is a horizontal sectional view of the same.

Referring to the drawings in detail, 1 do notes the upper section of thewind shield and 2 the lower section, and each of which consists of asheet of transparent material connected to a frame. The side bars of theframe of one section normally oppose the side bars of the other section.The side bars Specification of Letters Patent.

Serial No. 586,783.

of one section are hinged to the side bars of the other section, thehinge being so constructed that the section 1 can be angularly adjustedwith respect to the section 2, and maintained in its adjusted position.

The hinge includes a male member and a fem ale member, the former isreferred to gen erally by the reference character 3 and the latter bythe reference character 1. Each of the members of the hinge consists ofa split sleeve 5 provided with an extension 6 constituting an abutmentto arrest the movement of the female member, with respect to the malemember. The sleeve 5 of the member 8 is connected to the side bars ofthe section 2, while the sleeve 5 of the member 4 is secured to the sidebars of the upper section. The sleeve 5 of the member 4 is oppositelydisposed with respect to the sleeve 5 of the member 3.

The sleeve 5 of the member 3 is off-set, as at 7, and formed integralwith said ofi -set portion is a cup-shaped member 8 having its bottom 8secured in position by rivets 8 and formed with a centrally disposedscrew threaded opening 9, and with the bottom depending beyond the sideto provide an annular shoulder 10. The bottom of the cupshaped member 8is formed with a pair of oppositely extending rectangular openings 11,and the inner face of the side of the cup is cut away at 12, 13, formingrecesses, which open into the slots 11.

The sleeve 5 of the member 1 is formed with an off-set portion 14:, withwhich is formed integral a cup 15 provided with an opening in itsbottom, as at 16. Surrounding the opening 16 is an annulus 18 of hardmetal provided with a series of radially disposed grooves 19. Theannulus 18 is fixedly secured to the bottom of the cup 15, by thehold-fast devices 20. The cup 8 is of a height approximately half thewidth of the off-set portion 7, and the cup 15 is of a heightapproximately half the width of the off-set portion 14. The cups 8 and15 are positioned against each other, with the annular shoulder 10extending into the cup 15. The cup 15 is shiftably connected to the cup8, whereby the upper section 1 can be an gularly adjusted with respectto the section 2, when occasion so requires.

To maintain the section 1 in its adjusted position with respect to thesection 2, a pair of gripping blocks 21 are loosely mounted in the slotsor openings 11, and which are adapted to engage simultaneously in two ofthe grooves 19 to preventmovement of the cup 15, until the blocks 21 arereleased. The blocks 21 are maintained in the grooves 19 through themedium of a retaining plate 22, which is positioned in the cup 8 andabuts against the blocks 21. Bearing against the plate 22 is a coiledspring 23, which surrounds the threaded portion 24 of the shank 25 of aheaded bolt, the head of the bolt being indicated by the referencecharacter 26 and the smooth portion of the shank by the referencecharacter 27. The shank of the bolt extends through the cups 8 and 15,and the head of the bolt abuts against the outer face of the bottom ofthe cup 15. The smooth portion 27 of the shank 25 of the bolt ispositioned in the opening 16, whereby the cup 15, when released can berotated upon the said smooth portion 27. The threaded portion of thebolt 25 engages with the threaded wall of the opening 9, and therebyfixedly maintains the cup 8 in position. Mounted upon the threadedportion 2a of the shank 25 is a retaining cap 28, against which abutsthe spring 28. The cap 28 is adapted to be screwed on the threadedportion 24 of the shank 25 of the bolt and abut against the cup 8, thebody portion of the latter being of a suificient width to constitute abearing for the cap. hen the cap 28 is positioned against the cup 8, thespring 23 is compressed and the plate 22 forces the blocks 21 into apair of grooves 19 and maintains the blocks in the grooves. Thisoperation locks the male and female member of the hinge together. Theshank 25 of the bolt is somewhat elongated and projects outwardly fromthe cap 28 sutficiently to accommodate the couplings carried by theupper ends of telescopic or brace rods for the wind shield.

Vhat we claim, is:

A wind shield hinge comprising amale and a female member, a cup 8secured to and olfset with respect to one of said members, a cup 15secured to and off-set with respect to the other of said members, anannulus arranged within and fixedly secured to the inner face of thebottom of the cup 15, said cup 8 having its bottom projecting beyond itssides and into said cup 15 and provided with a pair ofoppositelydisposed slots, gripping blocks mounted in said slots andadapted to engage in said grooves to prevent movement of one of the cupswith respect to the other, a spring-pressed plate mounted in said cup 8and bearing against said blocks for maintaining them in the grooves, aspring extending in the cup 8 and engaging said plate, a bolt extendingthrough and projecting from said cups, and a cup engaging with said boltand abutting against said spring whereby the spring will engage theplate and maintain the blocks in the grooves.

In testimony whereof we ai'lix our signatures in the presence of twowitnesses.
